- trees they grow slower when there is too much Co2 in the air? For a long time, experts believed that more carbon dioxide in the atmosphere increased tree growth.
Un new study published Nature However, it suggests that trees in tropical rainforests around the world are not in a faster growth phase, even as CO2 levels in the atmosphere have increased due to polluting emissions.
If excess CO2 doesn't help trees, could it damage them? Peter van Slen, of the University of Wageningen, in the Netherlands, together with a team of Dutch researchers, examined over a thousand ancient trees of 12 different species in Bolibia, Thailand and Cameroon.
They found no evidence that Co2 could accelerate tree growth, a phenomenon that the scientific community does would have taken it for granted previously. According to experts, the results obtained in this study could question what was previously believed.
This would be another piece of the puzzlebut not definitive evidence of what happens to rainforest trees due to pollution and climate change. Yup hypothesizes than the oldest trees in the forests share CO2 with younger treesinstead of using it to accelerate your own growth.
The next experiments, which will be conducted in Brazil, will try to understand how the presence of Co2 can influence the growth of trees, thanks to specific monitoring. If the Co2 sharing hypothesis is confirmed, we may need to learn a lesson about sharing economy from our friends trees.
